Damien never found the river the woman walked.
Perhaps it was imaginary. Perhaps it was meant to represent the rift between the blackness and the whiteness, the area that no man had ever traversed.
If that was the case, then it wouldn't be here.
It was a bit of a shame for sure. Damien didn't necessarily need to see it anymore, but that water was symbolic. He wanted to experience it at least once.
He understood the source of the sorrow in his heart now. He also felt a deep sympathy that he didn't feel from the story alone.
He was understanding something too filled with emotion for it to be untrue.
The further his thoughts went down that path, the more the sorrow in his chest grew. It felt like Nonexistence was crying out, screaming into the void as it came face to face with its emotions.
He couldn't doubt and say that his perception of the scene was wrong anymore.
